Info

Probably one of the best kept secrets...the best engine builders use break-in roller rocker arms. With the extreme valve spring pressures racers use today, the initial run time can kill a camshaft in the first minute of running.

The big time engine builders use these 1.3:1 ratio rockers to allow a run-in time for the camshaft, then the 1.3:1 rockers are removed and the normal rockers are reinstalled and the engine is ready to race or dyno.

Polylocks are included.

Some parts are not legal for use in California or other states with similar laws/regulations
